Shams Charania of The Athletic and Stadium first reported the news. The Lakers waived forward Aric Holman to make room for Howard.
Arash Markazi of the Los Angeles Times noted Howard will be the first player in Lakers history to wear the No. 39 jersey.
Howard made only nine appearances for the Washington Wizards in 2018-19. He underwent an L4-L5 lumbar microdiscectomy last November and didn't return for the remainder of the season.
The injury continued his overall decline, a trend that arguably started with his trade to the Lakers in August 2012. Howard never meshed with Kobe Bryant, and the Lakers won 45 games before getting swept in the first round of the 2013 playoffs.
The 33-year-old has remained a consistent scorer and rebounder; however, he will now be moving to his sixth team in five seasons—five teams if you exclude his brief stint this summer with the Memphis Grizzlies—which largely speaks for itself.
According to ESPN's Adrian Wojnarowski, the Lakers made it clear to Howard that they'd release him if he ruffled any feathers in the locker room.
Wojnarowski reported Howard spoke with team officials, players and coaches to ease any doubts about his willingness to accept a lesser role. He added this has become a regular theme: "For years, Howard, 33, has sold an almost annual idea of a personal renaissance and epiphany, only to infuriate coaches and teammates with behavior that moved from selfish on the court to childish and disruptive off it."
Charania wrote Howard is expected to vie for Los Angeles' starting center position with JaVale McGee.
